It seems that the front right side of my ml320 is a little lower than the left. I have searched and it seems that the adjusting bolt at the back end of the torsion bar needs to be turned clockwise to raise it. I cannot find any reference as to how many full turns might be needed to raise one inch. Any direction is appreciated.

 

I'm not sure if there is any exact information out there on that. I would with a tape measure, measure the ride height on both sides. Decide which height you want to go with. Then, turn the other side until the height matches. Turning the bolt counter-clockwise lowers, clockwise raises.
